Would Young Professional
be a good advertising outlet
for online brokers?
The Young Professional
won’t
be a good advertising outlet for online brokers.
Because......
The average or mean number of transactions in
stocks, bonds or mutual funds made
in the last year by subscribes is 5.97,
which is

low.

Would this magazine be a good place
to advertise for companies
selling educational software and
computer games for young children ?
This magazine would be a
good

place to advertise for companies selling educational software and computer games for young children.

is relatively
higher
as compared to those
who don’t have it.
